(ULM Québec), departed St-Cuthbert (ULM Québec) Aerodrome (CCU2), Quebec, at approximately 1900, 1 with a student in the front seat and a pilot providing instruction sitting in the rear seat. For approximately 1 hour, the aircraft flew locally, completing several circuits at CCU2 and low-altitude flyovers of Runway 10.  \nAt around 2000, the aircraft landed. The pilot providing instruction and the student switched seating positions for the next flight. The investigation could not determine why they changed seats, or if this was common practice.  \nAt approximately 2008, the aircraft commenced a takeoff on Runway 10. During the initial climb over the runway, several engine backfires 2 were heard. The aircraft then commenced a steep right turn and entered a dive before it disappeared behind a pile of hay bales. The aircraft struck the ground in an agricultural field south of the runway (Figure 1) .  \nULM Québec’s personnel rushed to the site to provide assistance to the occupants, calling 911 on the way, and shut down the engine, which was still running at high rpm. The impact forces caused substantial damage to the aircraft. The 2 occupants received fatal injuries.  \n1 All times are Eastern Daylight Time (Coordinated Universal Time minus 4 hours) .  \n2 While bystanders saw or heard parts of the accident, none observed the entire accident sequence.  \nFigure 1. View of the aerodrome and the occurrence aircraft’s observed flight path (Source: Google Earth, with TSB annotations)  \nWeather information  \nThe 2000 aerodrome routine meteorological report (METAR) for Trois-Rivières Airport (CYRQ), which is located approximately 30 nautical miles (NM) east-northeast of the accident site, indicated winds from 230° true at 5 knots; visibility of 9 statute miles and a broken ceiling at 9500 feet above ground level. The weather at the time of the occurrence was not considered a factor in the accident.  \nCompany and aerodrome information  \nULM Québec Inc. is a Transport Canada (TC)–registered flight training unit under Subpart 406 of the Canadian Aviation Regulations (CARs) for the ultralight category. It operates at CCU2, a registered aerodrome located 2.6 NM northwest of the municipality of Saint-Cuthbert. CCU2 has a 1352 foot– long turf runway (Runway 10/28) and is mainly used by ultralight aircraft.  \nPilot and student information  \nRecords indicate that the pilot providing instruction had obtained an ultralight pilot permit in November 2018 and held a valid Category 3 medical certificate. However, he did not hold a flight instructor rating—ultra-light aeroplane to conduct flight training, as required under paragraph  \n425.21(2)(a) of the CARS Standard 425, Flight Training. He had accumulated approximately 100 total flight hours on ultralights. Nothing indicates that the pilot’s performance was degraded by physiological factors.  \nThe student had started his ultralight pilot training in October 2018. At the time of the accident, he had completed the theoretical training and accumulated around 10 total flight hours, all with ULM Québec. Most of his dual instruction flights had been completed with the occurrence pilot.  \nAircraft information  \nThe DTA Voyageur II 912S is a single-engine, 2-seat ultralight trike which uses weight-shift as a means of flight control. It is powered by a 100-horsepower, 4-stroke Rotax 912 ULS engine and a fixed-pitch carbon fibre 3-blade propeller (Figure 2) . The occurrence aircraft was equipped with optional dual controls and a DTA Diva wing allowing for a 472.5 kg maximum take-off weight.
